NA4906 Needle Roller Bearing with Inner Ring, 30mm Bore Dia, 47mm OD, 17mm Width

1.Needle Roller Bearings with Machined Rings and Inner Rings are separable-designed bearings with high load carrying capacity and stiffness.
2.These bearings are especially suitable for high dynamic loads or radial-limited installation.
3.Assembling inner and outer rings separately permits interference fits for shaft and housing.
4.For various applications such as automotive and truck transmissions, agricultural and construction equipment, pumps and compressors, and two-cycle engines, among others.
5.NOTE: Install with press machine or special tools instead of hammers because beating may to local deformation or brittle fracture.
